Arp 216

These Astrobin Debut Object is a pair of interacting galaxies located 240 million light years away in the constellation of Pisces at a declination of +4 degrees. In his Arp catalog, Dr. Arp classified this object into the category of Galaxies with Adjacent Loops.

NGC 7682 is the magnitude 14 barred spiral at lower left. It is a Seyfert galaxy with a diameter of 90,000 light years.

NGC 7679 is the disturbed magnitude 13 barred lenticular galaxy at upper right. It is also a Seyfert galaxy and is similar in size to our Milky Way, at 120,000 light years in diameter. I need to obtain more time on this one to see the faint star streams and interesting core area in more detail. This galaxy is also categorized as a starburst galaxy.

Detailed studies have found a huge neutral hydrogen (H I) bridge connecting these 2 galaxies, likely from a closer encounter long ago. This confirms that NGC 7682 is the likely source of the disturbance seen in NGC 7679.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
